The definition of a skate wheel bearing
and how skate bearings work.
What is a Skate Bearing?
Skate wheels turn freely because of an anti-friction
device called a bearing that is inserted between
each wheel and axle. The type of bearing used in
roller sports equipment is known as a "miniature
deep groove ball bearing".
How do Skate Bearings Work?
Skate bearings reduce the friction between a moving
skate wheel and a fixed, non-moving skate frame.
Each skate wheel requires two bearings - one on each
side. A bolt is threaded through the center of each
bearing and wheel assembly to attach it to the skate frame.
If you are using micro bearings, you might also need
a special adaptor or "sleeve" to make the bearing fit
nicely in your wheel.
